Support configurable options to control how link bandwidth is handled by the receiver. The default behavior is to automatically honor the link bandwidths received and use it to perform a weighted ECMP BUT only if all paths in the multipath have associated link bandwidth; if one or more paths do not have link bandwidth, normal ECMP is performed among the multipaths. This behavior is as recommended by https://tools.ietf.org/html/draft-ietf-idr-link-bandwidth. The additional options available are to (a) completely ignore any link bandwidth (i.e., weighted ECMP is effectively disabled), (b) skip paths in the multipath which do not have link bandwidth and perform weighted ECMP among the other paths (if at least some paths have the bandwidth) or (c) use a default weight (value chosen is 1) for the paths which do not have link bandwidth. The command syntax is bgp bestpath bandwidth <ignore|skip-missing|default-weight-for-missing> Signed-off-by: Vivek Venkatraman <vivek@cumulusnetworks.com> |
